Professor David Grayden is Deputy Head (Academic) of the Department of Electrical and Electronic Engineering and Leader of the Bionics Laboratory in the Centre for Neural Engineering, The University of Melbourne .

Prof Grayden's main research interests are in understanding how the brain processes information, how best to present information to the brain using medical bionics, such as the bionic ear and bionic eye, and how to record information from the brain, such as for brain-machine interfaces. He is also conducting research in epileptic seizure prediction and electrical stimulation to prevent or stop epileptic seizures. He has research linkages in Australia with Cochlear Limited, the Bionics Institute, St Vincent's Hospital Melbourne, Royal Melbourne Hospital, NICTA, University of South Australia, Florey Institute for Neuroscience and Mental Health.  He also has international research linkages with Illmenau University of Technology, Germant and University of Maryland, USA.  He supervises a number of postdoctoral researchers and PhD and Research Masters students.

Prof Grayden teaches in the Bioengineering and Biomedical Engineering programs.  He teaches in the subjects: BioDesign Innovation, Neural Information Processing, Biosystems Design, and Biomedical Engineering Design Project.  He also contributes to the Neuroscience Research Training course modules.
